Abstract
A projector and a projection method are provided. The projector is coupled to a display card and includes a light source, a light valve, a projection lens, and a processor. The light source provides an illumination beam. The light valve converts the illumination beam into an image beam. The projection lens projects the image beam to the outside of the projector to form an imaged image. The processor receives an input image signal from the display card, and generates a control signal corresponding to the input image signal according to a refresh rate of the input image signal. When the refresh rate is greater than a threshold, the imaged image has a first resolution. When the refresh rate is less than the threshold, the light valve performs a pixel shifting operation, so that the imaged image has a second resolution. The first resolution is less than the second resolution.
